As public health officials work to contain the mysterious, pneumonia-like virus that has gripped Asia, people are taking measures to protect themselves against the expanding outbreak.
The yet-unnamed coronavirus, a family of viruses that affect the respiratory tract, has killed 41 people and sickened more than 1,000 at last count, including a man in Washington state and woman in Chicago who both had recently traveled to Wuhan. The virus is believed to have started in a livestock market in Wuhan and jumped from animals to humans.
